Receptor mediated endocytosis
Engulfs specific substances and have bound to a receptor
Phagocytosis
Engulfs solid particles
Pinocytosis
Engulfs liquids
Hypotonic solutions
Cells gain water
Hypertonic
Cells lose water
Isotonic solution
No net gain and no net loss of water
Exocytosis
Release of substances/particles from cell (NEEDS ATP)
Endocytosis
Moves a suns stance into the cell inside (NEEDS ATP)
Active transport
Primary/endocytosis(direct use of ATP)
Secondary/exocytosis (indirect use of ATP)
Moves substances concentration gradients
Facilitated diffusion
Diffusion across the cell membrane through ion channels or transporters(NO ATP)
Osmosis
Diffusion of water (NO ATP)
Diffusion
Movement from a region of higher to lower concentration (NO ATP)
Active process
NEEDS ATP
Passive process
NO ATP
Chromatin
Stores needed information for protein synthesis
Nucleolus
Site of ribosome production
Ribosomes
Produce proteins
Lysosomes
Act like cells garbage disposal
Cytoskeleton
Helps maintain shape
Centrioles
Separates chromosomes during mitosis
Vacuole
Might store food and nutrients waist or get rid of extra water
Mitochondria
Site of aerobic respiration
Golgi apparatus
Modifies stores and packages proteins from ER
Smooth ER
Contains enzymes that perform synthesis of membrane lipids and detoxification of drugs
